I have been looking for a solution to share bookmarks of online games with young children that is more visual that just a list or web addresses. I used to create a web page with labels and icons that were hyperlink enabled. This is very time consuming. I have just started using Simply Box.
Simply Box acts as a Firefox add on. It lives in your toolbar. All you do is whenever you see a game (or web page) that you want to add, you click the button 'Box it' and then draw a box over the area of the screen that you would like to have as the thumbnail hyperlink.
When you have created the capture, you simply drag it to one of your containers at the bottom of your screen and it has been captured. When you are satisfied with your collection, you can share it with others. They will see a page of click-able icons that you have made. This is fantastic for young learners as they respond more to images rather than text.
